SMITFI : ON THE GENUS ASTARTE. 207 



Habitat. — Portland Harbour, Maine (Mighels). Eastport, 

 Grand Manan, Newport, and other localities on the east coast of 

 North America, also Newfoundland. 



The fossil A. omalii of the Crag, agrees with this species in 

 having broad ribs and deep interjacent furrows, but in that species 

 the beaks are more produced, peculiarly flattened, more acute, 

 and the apical angle much sharper. The edges of the lunule and 

 hinder ligamental area are also much more sharply defined. 

 These in my opinion are sufficient distinctions to separate these 

 two forms. Dr. Gwyn Jeffreys however holds a different view, 

 and unites both these with the A. sulcata of Da Costa. Verrill 

 states that "this is by far the most abundant species on the 

 northern coast of New England. It ranges from Cape Cod to 

 Labrador."
